Create a seamless documentary photograph of this same adult repairman pushing this same old dark-green bicycle along the broad white salt embankment in image 2. Preserve his face, straw hat, indigo shirt, tan trousers, shoes and the bicycle frame, handlebars and two wheels. Preserve the pink ponds, white salt texture, horizon and perspective of image 2. Place the complete man and bicycle naturally on the foreground embankment, with feet and both tires contacting the ground. Match scale and upper-left sunlight, with physically consistent contact shadows. One man, one bicycle, no collage borders, no duplicate limbs or wheels. No advertisements, brands, logos, signatures, text or watermarks.",
